Bearing wheel hub unit () is provided with a mounting flange () which is integral with an inner race () of the bearing () in order to mount a wheel, and with a centering collar () which extends from a frontal surface () of the flange () to permit the centering of the wheel in relation to the unit (). The centering collar () produced, preferably of alloy, in such a way as to be independent of the mounting flange (), and is assembled with the flange () by fixing onto the frontal surface ().

Bearing wheel hub unit

A hub-bearing assembly for the wheel of a motor vehicle includes a rotatable hub () having a radial flange () with bores () formed therethrough. Wheel fastening studs () each have a stem () inserted non-forcedly through a respective bore (). The studs () are fixed to the flange () by an adhesive or cementing material.

A hub-bearing unit () has a rotatable outer race () fixable to a wheel and an inner stationary hub () forming a passage () for pressurized air coming from a source of pressurized air mounted onboard of a vehicle. Tightly fitted on the axially outer side of the unit () is a cylindrical cover () defining with the unit () an airtight chamber () communicating with the passage (). The cover () has a through bore () for establishing air communication between the chamber () and a tube (A, B) for conveying pressurized air to the tire. The cover has an outer wall () with a cylindrical portion () axially protruding beyond the hub-bearing unit () so as to provide a cylindrical surface for centering the wheel of the vehicle.
